UNITED STATES JAMES A. CARLTON, F NEWARK, NEW JERSEY.

PAPER Application filed January To all whom it may concern Be it known that I, J AMES A. CARLTON, a citizen of the United States, and a resident of Newark, in the county of Essex and State v of New Jersey, have invented new and useful Improvements in Paper Joggers, of which the following is a specification.

This invention relates to a device commonly known as a paper jogger for evenly stacking or piling sheets of paper or the like as they are discharged from a machine, for example, a multigraph printing machine.

Paper joggers are well-known in the printing press art, and are usually large,

complicated and expensive devices, which apparently accounts for the failure of or relatively slow adoption of similar devices for multigraph and other small printing machines.

Accordingly one object of my invention is to provide a paper jogger embodying novel and improved features of construction which is particularly adapted for use with multigraph and other similar printing machines, although the invention is not limited to such use.

Another object is to provide a device of the character described which can be easily and quickly applied to an ordinary multigraph machine without structural modification thereof.

Further objects are to provide a novel and improved paper jogger which can be easily and quickly adjusted to accommodate paper of different widths; to provide such a device embodying a small number of simple and inexpensive parts, and to obtain other results and advantages as may bebrought out by the following description.

In the accompanying drawing I have shown a paper jogger particularly designed for use in connection with known multigraph machines, but it will be understood that this is mainly for the purpose of illustrating the principles of the invention and that the device is susceptible of use with other machines and the detailsof construe lion can be varied without departing from the spirit or scope of the invention.

Referring to said drawing in which the same characters ofreference designate corresponding and like parts throughout the several views,

graph machine, the machine being fragmentarily shown;

Figure 2 a transverse vertical sectional view taken on the line 2-2 of Figure 1, and

Figure 3 is an enlarged perspective view of the jogger.

Specifically describing the present embodiment of the invention, the reference character A designates a table to receive sheets of paper as they are discharged from a multigraph machine 13, said table being of the known construction and including two vertical sideboards C and D one or both of which are adjustable toward and from each other transversely of the table A to accommodate pa er of different widths.

It will be un erstood thatthe sheets of paper are automatically discharged from the machine B and that the sideboards C and D are so positioned on the table A and relatively to each other as to receive the sheets of paper between them as shown in Figures 1 and 20f the drawings. 'A wire frame E is supported from the machine B over the table A to prevent the papers from flying outwardly over the tops of the sideboards C and D and another wire frame F is arranged at the outer end of the table A to prevent papers from sliding endwise from the table. 1 I

In accordance with the invention, one of the Sideboards, in the present instance the board C, is freely movable toward and from the other board D,and said board C is normally spaced from the board D a distance which provides a small space between said board C and the edge of a sheet of paper which has its other edge bearing against the board'D, as clearly shown in Figure 2. The papers as they are discharged from the machine fall upon the stack G more or less irregularly, as indicated by the top sheet of the stack in Figure 2, and the board C is periodically and synchronously with the discharge of thepapers from the machine 13, moved toward the stack so as to push the irregularly discharged sheets against the board D, as shown in Figure 2, so' that the sheets of paper are arranged in a stack having even edges.

The jogger includes a body portion 1 which is preferably formed of cast metal and is provided at one end with lugs 2 formed with openings 3 to receive fa ning members such as screws Al, said lugs 2 being secured to the underside of the table A. by means of the screws 4t, as shown in Figure 2.

The body portion 1 is also formed with a pair of spaced upwardly projecting bearing posts 5 in which is slidably mounted rod 6 carrying at one end a plate 7 having a plurality of openings 8 to receive for securing the plate 7 to the movable sideboard C. A. tension spring 9 has one end connected to the plate 7 as at 10, and the other end connected to a stud 11 mounted on a vertical flange 12 of the body portion 1, said spring tending to draw the plate 7 toward the body portion 1 until the plate abuts the outer bearing post 5, as shown in l igure 3. A sleeve 13 is adjustably mounted on the rod. 6 between the bearing posts 5, said sleeve carrying a set's'crev lei where by the sleeve may be fixedly secured to the rod 6 at various positions.

A. bell-crank lever 15 is pivotally mounted on the body portion 1 by a pivot bolt 16, and one arm of said lever is bifurcated or forked as at 17 to embrace the rod (3 at the rear of the sleeve 13, as clearly shown in Figure 3. The other arm of the bell-crank lever is provided with a, transverse opening 18 in whichis slidably arranged rod 20 which has one end connected as at 21' to a crank arm 22'on a shaft 23 of the multigraph machine B. This crank arm 22 and shaft 23 are found on a known type of machine and are commonly utilized for operating the paper feed mechanism through a l nk 24-. A collar 25 is slidably mounted on the rod 20 to engage the end of the bel crank lever as shown in Figures 1 and 3, and a spring 26 is interposed between said collar and a sleeve 27- slidably on the rod but capable of being fixed thereto by means of a set screw 28. The extremity of the rod 20 is preferably provided with a cotter pin or the like 29 to prevent the rod from pulling out of the opening 18 in the bell-crank lever.

In the operation of the device, the body portion 1 is secured to the table A and the plate 7 is secured to the sideboard C, as shown. The sideboard C may then be ad justed relatively to the board D by manually sliding the rod (3 to move the plate 7 toward or away from the outer bearing post against the influence of the spring 9. While the rod is so held, the sleeve is adjusted on the rod to bring it substantially into engagement with the forked end 1'? of the bell-crank lever, whereby the board C is held in the adjusted position by the sleeve 13 and set screw 14. The rod 20 is then connected at 21 to the crank arm 22 and the sleeve 27 adjusted so as to cause engagement of the collar 25 with the end of the bell-crank lever. The machine B is then started in operation and upon each revolution of the crank arm 22, the board C is moved through longitudinal movement of the rod 20, oscillation of the bell-crank lever 15 and sliding of the rod 6, toward the board D, as shown in dotted lines in Figure 2, as to push the sheet against the board D. The movement of the board C toward the board D must be properly related to the discharge of eac sheet of paper, that is the board C must move toward the board D after each sheet has been discharged from the machine and moved away from the board D before the next sheet is discharged. In the arrangement shown, this synchronism is obtained through the crank arm 22 which has a certain relation to the paper feed mechanism of the machine B. It will thus be observed that the board. (7 is automatically operated to produce even stacl-zing of the sheets of paper on the table A, the board C being moved in one direction by power from the machine B and in the other direction by the spring 9. The spring 26 enables a certain relative movementof the rod 20 and. the bell-crank lever 15 to prevent excessive pressure of the board C against the stack of paper, at the same time producing the necessary yielding pressure against the stack.

It should be noted that the sleeve 13 enables adjustment of the rod 6 and the sideboard C in the direction of movement 01"" the rod 6 toward or from the board D, rela tively to and independently of the bellcrank lever 15. This is particularly important since it enables easy and quick adjustment of the jogger to use with paper of a certain width and permits adjustment of the movable sideboard C to correspond with the particular point of discharge of the sheets from the machine. The device is usually adjusted by running a sheet nearly through the machine and arranging the stationary sideboard D about three quarters of an inch from the corresponding edge of the sheet. The sideboard O is then moved toward the board D by sliding rod 6 to push the sheet against the board D, whereupon the sleeve 13 is set against the outer bearing post 5 and the screw 14. tightened. The collar 5, spring 26 and sleeve 2? enable ad- 'iustment ot' the connection of the rod 20 to the bell-crank to accommodate diilerent ma chines and also to accommodate sheets of paper of dill erent widths in the same staclr such as might occur from variations in the cutting of different lots of paper.

Nhile I have shown and described the in vention in connection with a power operated multigrap'h machine, it will be understood that the jogger may be used in connection with other types of machines and hand-op erated machines without material modifica tion of the structure of the jogger or the machine. Therefore T do notdesire to be understood as limiting myself in the construction and use of the invention except as may be required by the following claims when construed in the light of the prior art.
